We reassure ourselves that our brains' 'hard drives (HDs)' are too full to handle the new information that comes in daily. But a Johns Hopkins neuroscientist suggests that our aging brains are unable to process this information as 'new' because the brain pathways leading to the hippocampus become degraded over time. As a result, our brains cannot accurately 'file' new information."
